3 Claims. (Cl. 198-220) Our invention rel-ates to improvements in vibrating conveyors for conveying comminuted material through closed conduits. a

The object of'the invention is to provide a means, of handling material continuously without creating dust, but to convey said material horizontally or up inclines of up to thirty degrees above the horizontal dependent upon the nature of the material carried.

A further objectis to provide a conveyor which will convey comminuted material from point to point with great economy of motivating power.

The device is illustrated in the accompanying drawings, in which:

Figure 1 is a longitudinal elevation of the invention set to deliver material horizontally.

Figure 2 is an enlarged fractional elevation showing the disposition of the driving motor.

Figure 3 is a section taken on the line 3-3 of Figure 2.

Figure 4 is a section taken on the line 44 of Figure 3 and showing a typical connecting rod .disposed between the two conduit pipes.

. Figure 5 is a plan of the pipe mounting.

Figure 6 is an enlarged section taken on the line 6'6 of Figure 1 and showing the spring mounting box.

Figure 7 is a detailed section of the spring mounting box taken on the line 7--7 of Figure 6.

1n the .drawings like characters of reference indicate corresponding parts in each figure.

The numeral 1 indicates a base from which are erected a plurality of spaced pairs of side plates 3. Each pair of plates is fitted on its outer face with upper and lower spring boxes 4 and 5 respectively. The spring boxes are preferably circular as shown particularly in Figure 7 and are provided with adjustably mounted eye bolts 7 to.

each of which a tension spring 8 is connected. The springs 8 and the eye bolts are disposed radially within the boxes and a bearing 10 is connected to the inner free ends of all the springs.

Horizontally mounted between the side plates 3 are upper and lower pipes 12' and -14 having longitudinally spaced pairs of trunnions 15 which may be fitted to sleeves 16 surrounding said pipes. The trunnions extend through apertures 17 in the plates 3 and are supported in the bearings 10. The apertures 17, as shown in Figure 6 only, are substantially three times the diameter of the trunnions so that said trunnions are free to oscillate within the openings during vibration of the pipes 12 and 14.

It will be noticed that the trunnions of the upper pipe 12 I are disposed in the direction of the material being conveyed forwardly of the trunnions on the pipe 14. The pipes 12 and 14 are separately connected by means of resilient sleeves 18 to pipe bends 19 and by further resilient sleeves'20 to a feed hopper 21, or any other source of material to be conveyed.

A platform 22 is erected on legs 23 above thepipes 12 and 14 and adjacent said platform a tranverse sleeve a 25 is fitted to the upper pipe 12 to support a horizontal r 2,936,876 Patented May 17, 1960 shaft 27. The shaft 27 is journalled in a bearing 28 and, is belt and pulley driven at high speed from a motor 29 mounted upon the platform 22. The shaft 27"is provided adjacent each end with an eccentric 30 which engages the upper end of a connecting rod 32. It will be obvious that the springs 8 in the-spring boxes 4 and 5 will be adjusted to normally support the pipes 12 and 14 when the axes of the eccentrics 30 are lying in the.

39 will exert pressure against each other, but which will allow a certain lagging movement of the pipe 14 relative to the pipe 12.

Where the pipes 12 and 14 are ofsubstantial length or the material to be conveyed is heavy, supplementary supporting arms 41' may be provided. These arms are particularly illustrated in Figure 6 and are provided with end and central apertures 42 and 43 respectively, all of which are fitted with rubber bushings 45 and 46. The bushings 45 of the arms are mounted on the trunnions 15 and the bushings 46 are mounted on'center pins 48 which extend inwardly from the side plates 3. The bushings 45 and 46 permit the arms 41 to move to a very slight extent relative to the side plates 3 and the trunnions 15, but it has been found that the movement of the arms .is mainly a rocking motion about the center pins 48. The arms 41 and their associated parts form pipe will swing in an anticlockwise direction about an ovate orbit so that the material in the pipe will be thrown upwardly and rearwardly while the springs 8 in the spring boxes supporting the upper pipe, are striving to counteract said movement. The movement of the pipe 12 on its over stroke or along the upper part of its orbit will initiate an upward and leftwards movement in the lower pipe 14, but this movement will be retarded out of phase with the first-named movement due to the rocking of the lower members 34 about their pivot pins 35. Since the oscillation cycles of the two pipes 12 and 14 are outof phase, the load on the motor is substantially constant after the said pipes have become filled to their normal operating condition.

What we claim as our invention is:

1. A vibratory conveyor comprising a plurality of standards spaced apart, each of said standards having two side members and each of said side members being provided with two sets of radially mounted springs, the springs of each set being connected to a pipe supporting bearing, a pairof parallel pipes each having trunnions, each trunnion being seated in the supporting bearing of a set of springs whereby each of the pipes may oscillate with respect to and out of phase with the other of said pipes,-'a driven shaft carried by and mounted for rotation on one'of said pipes, said shaft having an eccentric rotatable therewith, a connectingrod connected with the eccentric to be moved thereby, said connecting rod being connected to the other pipe to oscillate it as the eccentric is rotated, resilient couplers connecting the pipes at intervals of their length and means for" rotating the shaft. v. 5 2. In a vibratory conveyor as claimed in claim 1 wherein each resilient coupler is resiliently and pivotally mounted'upon a fixed part of the conveyor and is connected at its ends to the pipes.

3. .In a vibratory conveyor claimed in claim 2, 10 317,730

wherein the connection of the resilient couplers to the pipes is through the pipe trunnions.
